Why Ni positive 2 and iron positive 3 ions have different Rf values?

Rf values are determined by the polarity of the substance tested. Even though these atoms may have similar electron configuration, it is not identical, and neither are their Rf values.

In the compound iron II carbonate the ratio of iron II ions to carbonate ions will be?
One to one
How can iron form two separate compounds with oxygen?
Iron can form two different ions, Fe2+ and Fe3+. Because of their different charges these ions will bond differently with anions such as oxide (O2-) As a result we get the compounds FeO and Fe2O3. There is a third oxide which is a combination of the two: Fe3O4
What are the individual ions in iron II sulfate?
The individual ions in FeSO4 (Iron II sulfate) are Fe2+ and SO42-.
Why does a magnet pick up iron in a mixture of iron and sulfur but not in a compound of iron sulfide?
Iron's magnetic properties are due to the configuration of its electrons when it is in its elemental form. In iron sulfide iron is in the form of positive ions rather than neutral atoms. This changes the electron configuration and thus how iron will respond to a magnetic field.
How does iron combine with other elements to form chemical changes?
It is a chemical change because bonds between atoms have changed. Iron is oxidized and gains iron-oxygen bonds. These new bonds absorb light differently than iron-iron bonds, so rust is a different color.
Is plutonium positive or negative?
The neutral atom of plutonium has no charge.
Why is an iron ion is attracted to a sulfide but not a zine ion?
An iron ion and a sulfide ion have positive and negative charges respectively, and they attract each other. But having positive charges in both, iron ions do not attract with zinc ions.
Iron ions with a positive 2 charge and a positive 3 charge are called what?
Fe 2+ is Ferrous Fe 3+ is Ferric
Do ions have ions?
Ions are atoms that have either gained or lost electrons. Ions are normally formed by chemical processes. For example the rusting of Iron yields various types of Iron Oxides. Iron metal and oxygen gas both become ions. So when an atom becomes an ion through chemistry it always has a counter-ion (one positive and one negative). Some ions can vary in their charge depending on the situation, for example Iron often has a 2+ charge but can also easily have a 3+ charge. However, this is not formally considered "an ion of ion."
Fe2O3 is named iron oxide because it contains which type of iron ions?
Fe2O3 is named iron oxide because it contains Fe+ ions.
What ions are found in rust?
As rust is iron that is returning to a more stable state then most of the ions is iron

What elements form two or more ions with different ionic charges potassium calcium fluorine iron or oxygen?
There are two possible options here: Iron and oxygen
